If you want to make yet more improvement and replace the existing wiring for something altogether more robust then you will need
1 x FH020AA
2 x Furukawa Connectors
1 x 4 way am-phenol Connector
1 x 3 way am-phenol Connector
Cut the plugs from the 3 yellow wire coming out from the stator and and the red / green wires then replace with the weatherproof amphenol type plugs
Theses ones
Make up a lead with the other half of the Amphenol connectors at one end and the Furukawa connectors on the other
Furukawa
Amphenol
Hopefully you'll end up with something looking like this one
Have Fun
